A sick bird naturally will try to hide its health issues.

The birds try to add a door to Peep's can.

And from the foot of the strange ship some birds tried to rise.

The bird howled, shut its eyes tight, and tried to turn in the air.

These birds of the mind were trying to stop her.

While lying on the lawn a large bird tries to approach him.

Little wonder, then, that early birds try to advertise their arrival hour.

I think the other bird was trying to hold up this guy.

Flightless or not, the bird was trying to take to the air.

"That bird won't try to hold us back again," he said grimly.
